Generate a range of hex numbers in format

i need to create a function in python to generate number in hex from 00:00:00 to FF:FF:FF
the out put can be a string but formated always 6 char seprate by ":"
so it should look like this

0 = 00:00:00
1 = 00:00:01
...
2816 = 00:0B:00
...
16777214 = FF:FF:EF
16777215 = FF:FF:FF

>Solution :

Try this :

for dec_ldev in range(0,16777215):
    hex_ldev = hex(dec_ldev)[2:].zfill(6)
    print("{}{}{}:{}{}:{}{}".format('',*hex_ldev))
